Question:
Reportability--Ovary: Is an ovarian serous borderline tumor with microinvasion with serous tumor aggregates (3 mm in greatest dimension) in 2 of 10 pelvic lymph nodes reportable? See Discussion.
Discussion:
SINQ 20170043 is a similar question about an ovarian mucinous borderline tumor with microinvasion, but the answer seems to be specifically referencing mucinous tumors only. It is unclear if that SINQ could be applied to this case. In addition, we were not sure how to interpret the nodal involvement. The physician assessment after surgery was low grade serous carcinoma, chemo not recommended and letrozole started.
Answer:
Ovarian serous borderline tumor with node implants is not reportable; it is a borderline neoplasm. However, if the oncologist believes he or she is dealing with a low grade serous carcinoma rather than a borderline tumor, this case is reportable. We recommend that you determine whether the diagnosis of low grade serous carcinoma, chemotherapy not recommended, is based on the pathological findings or on something else before reporting this case.
